<-- looks like it works again.
well, as cool as my rank is so far, I'm kinda miffed that there are no more unlocks to look forward to. It's essentially become a treadmill with no incentive or reward, it's purely for looks and really doesn't do anything besides give you some pointless experience bar to look at.
also, is it just me or does it annoy you when you login to see the little summary window showing your next unlock as "undefined" with like a broken graph or something. Definitely feels like the xp/unlock system was a bit rushed compared to some elements of the game.
